NASA Female Astronaut Reveals Space Station Toilet System Said Nothing Is Missing

When she lives in space, she must also master a subtle process: how to use the toilet in space. According to Dr. Whitson, being a member of the International Space Station research team is not only satisfactory but also exciting. But she also admitted that she would not miss the bathroom that cost $ 19,000. The official name of the toilet installed in the orbital laboratory is the waste and sanitation finishing bay.

The astronaut said: "The space station is still not compared to a real hotel. I call it a camping trip." The problem with doing anything in a weightless environment is that the item will fly if it is not fixed. And rebound everywhere. Space station toilets are no exception to this problem, so astronauts will be equipped with as many tools as possible to keep the space station tidy and hygienic.

She claims that it is relatively easy to urinate with the space station's toilet, thanks to a funnel device and an exhaust fan for collecting urine. It seems that anything on the International Space Station will not be wasted, and the collected urine will become drinking water after more than one week of filtration.

Dr. Whitson said: "We want to create a closed circulatory system, which means that we must recycle all the water." About 80% to 85% of the liquid waste is recycled into water, and the rest will be disposed of. . However, when astronauts use the toilet stool, they will face a greater challenge.

Dr. Whitson said: "The stool is more challenging because you have to work hard to target a fairly small target." The narrow space station toilet absorbs all excrement through a toilet hole about the size of a plate. Astronauts need to use leggings to secure themselves and be convinced that a vacuum cleaner-like toilet can be working.

After the astronauts complete the toilet, the excreta is sealed in a plastic bag and then processed by astronauts. However, system failures can occur from time to time, which is quite annoying for astronauts who want to go to the toilet.

Dr. Whitson said, “When toilets are full of fecal material, you must wear rubber gloves and compress them.” And sometimes, astronauts have to capture the debris that floats in narrow space stations. The solid waste collected by the station toilets will be mixed with other garbage collected by the space station and will be launched back to Earth. They will bring spectacular fireworks when entering the atmosphere.

According to NASA, all astronauts on the space station are consciously observing health regulations as they are on Earth. Astronauts normally sleep, eat, bath and use the toilet. The only drawback is that they need to float in midair.
